Interested to incorporate a subsidiary of my company there. And to live there ? Only if life is better than in Montenegro I'll have to figure it out :)
San Remo has a growing expat community, which helps in acclimating to a new culture and new language. You can stay connected through the expats living there as your Italian develops overtime. Good luck!
Sanremo is great for living with a family, but school choice is always very individual. You may find that the local schools are right for you. I would come and assess their level on site. There are good international schools in Monaco, Genoa, Como, Milan as well.
